The present invention relates to a polycarbonate resin composition,
Specifically, the present invention relates to a polycarbonate resin composition that has excellent impact resistance and heat resistance, has an extremely small molecular minimum during molding, and has good moldability without causing coloration. Conventionally, polycarbonate resins have been widely used as electrical and mechanical parts because of their excellent mechanical properties such as impact resistance, electrical properties, heat resistance, and the like. Furthermore, in order to improve the mechanical strength and heat resistance of this polycarbonate resin, glass fibers are also mixed. However, when glass fibers are mixed, it is necessary to strictly set molding conditions such as molding temperature and molding pressure from the viewpoint of fluidity during molding and dispersion of glass fibers. The most common polycarbonate is one produced using phenol or paratertiary butylphenol as a molecular weight regulator. However, when glass fiber is mixed with these general polycarbonates, moldability is not sufficient. Therefore, if the molding conditions are made gentler, the glass fibers will be less dispersed and a sufficient reinforcing effect will not be obtained. On the other hand, if the molding conditions are made too strict, the molded product may become discolored or deteriorate in quality.
In particular, polycarbonate has the disadvantage of poor impact resistance, which is its most important feature. The present inventors have discovered that an excellent polycarbonate resin composition that eliminates the drawbacks of these conventional polycarbonate resin compositions can be obtained by mixing polycarbonate having a specific terminal group with glass fiber, and has developed the present invention. It was completed. The present invention is based on the formula

性測定結果を第1表に示す。It can be easily produced by reacting divalent phenol and phosgene using a compound represented by the formula. For example, in the phosgene method, when divalent phenol dissolved in an alkaline aqueous solution is reacted with phosgene in the presence of an inert organic solvent, the above-mentioned molecular weight regulator is added before or during the reaction to perform an interfacial polycondensation reaction, thereby forming a polycarbonate. is obtained. Polycarbonate can also be obtained by the pyridine method, in which divalent phenol and the above-mentioned molecular weight regulator are dissolved in pyridine or a mixed solvent of pyridine and an inert solvent, and phosgene is blown into this solution to react. The polycarbonate thus obtained is purified and powdered by conventional methods. In the present invention, the above-mentioned molecular weight regulators may be used alone or in combination of two or more. Examples of the molecular weight regulator represented by formula (A) include paracumylphenol. Further, as the molecular weight regulator represented by formula (B), for example, paranonylphenol, paratertiary octylphenol, paradodecylphenol,
2-(3,5-dimethylheptyl)-phenol,
4-(3,5-dimethylheptyl)-phenol,
Examples include 4-(1.1.3.3-tetramethylbutyl)-phenol. Furthermore, examples of the molecular weight regulator represented by formula (C) include α-naphthol and β-naphthol. Examples of divalent phenols used as raw materials include hydroquinone, 4,4'-dihydroxydiphenyl, bis(4-hydroxyphenyl)alkanes (especially bisphenol A [2,2
-bis(4′-hydroxyphenyl)propane]),
Bis(4-hydroxyphenyl)cycloalkane, bis(4-hydroxyphenyl)oxide,
Examples include bis(4-hydroxyphenyl) sulfide, bis(4-hydroxyphenyl) sulfone, bis(4-hydroxyphenyl) ketone, and halogen-substituted compounds thereof. The polycarbonate resin composition of the present invention can be obtained by mixing the above-mentioned polycarbonate having end groups and glass fiber by a known method.
In the present invention, the mixing ratio of polycarbonate and glass fiber is 90 to 50% by weight of polycarbonate,
Preferably 90-60% by weight to 10-50% glass fiber
% by weight, preferably 10-40% by weight. Outside this range, the desired effect cannot be sufficiently obtained. An inorganic filler, a flame retardant, a stabilizer, a coloring agent, etc. can be appropriately added to the polycarbonate resin composition of the present invention, if necessary. The polycarbonate resin composition of the present invention may be mixed using an extruder or the like, and injection molding or the like may be used for molding. The polycarbonate resin composition of the present invention eliminates the above-mentioned drawbacks of conventional polycarbonate resin compositions mixed with glass fibers and has excellent properties. In other words, the polycarbonate resin composition of the present invention has good moldability, shows very little molecular weight decrease during molding, and is free from coloration.
It also has excellent heat resistance and impact resistance. Therefore, it is useful for electrical parts, mechanical parts, automobile parts, etc. Next, examples of the present invention will be shown. Example 1 A stirring tank with a jacket equipped with three swept blades,
1.6 N caustic soda aqueous solution 15 and 2630 g of bisphenol A were added, mixed and dissolved, and methylene chloride 7 was further added thereto. Next, phosgene was blown into this at a rate of 1.1 kg/hour while stirring. The reaction temperature was kept below 30°C by passing cooling water through the jacket, and when the pH reached 11.5 after 90 minutes, the blowing of phosgene was stopped. After the stirring was stopped and the mixture was left standing to separate the reaction solution into two layers, the aqueous solution in the upper layer was separated and removed. Bisphenol was added to the methylene chloride solution of the polycarbonate oligomer thus obtained.
An aqueous solution of 790 g of A dissolved in a 1.7 N aqueous caustic soda solution, 400 ml of a 48% caustic soda aqueous solution, 136 g of paracumylphenol as a molecular weight regulator, and 2.7 g of triethylamine as a catalyst were added and stirred to initiate a condensation reaction. It started. Cooling water is passed through the jacket to maintain the reaction temperature.
After about 1 hour while maintaining the temperature at 30° C. or lower, stirring was stopped after confirming that the molecular weight had become sufficiently high. The condensation reaction solution thus obtained was dissolved and diluted in methylene chloride 18, thoroughly washed with water to remove impurities, and then heated and concentrated using a kneader to obtain a powdered polycarbonate. The molecular weight of the obtained polycarbonate was 25,300. Mix 85 parts by weight of sufficiently dried polycarbonate powder and 15 parts by weight of glass fiber (length 6 mm),
Pellets were made using an extruder with a 30 mm vent, and injection molding was performed at a molding temperature of 340°C to obtain a molded product. The resulting molded product had good dispersion of glass fibers and was free from coloration. Table 1 shows the results of measuring the physical properties of the molded product obtained. Example 2 Paranonylphenol 138 as a molecular weight regulator
A molded article of a polycarbonate resin composition was obtained in the same manner as in Example 1, except that the same procedure was used as in Example 1. Table 1 shows the results of measuring the physical properties of the molded product obtained. Example 3 A molded article of a polycarbonate resin composition was obtained in the same manner as in Example 1 except that 144 g of β-naphthol was used as the molecular weight regulator. Table 1 shows the results of measuring the physical properties of the molded product obtained. Comparative Examples 1 to 2 Using 96 g of paratertiary butylphenol and 60 g of phenol as molecular weight regulators,
Otherwise, a molded article of a polycarbonate resin composition was obtained in the same manner as in Example 1. Table 1 shows the results of measuring the physical properties of the molded product obtained.
